:PILE-WIRE AND PINCERS FOR WEAVINGPILE FABRICS.

Specification of Letters Patent No. 9,363, dated November 2, 1852.

To all whom it may concern:

Be it known that I, ERAs'rUs B. BIGELow, of Clinton, in the county oflVorcester and State of Massachusetts, have invented certain new anduseful Improvements in Pincers and Pile-fires for Veaving Pil-edFabrios, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, which form a part ofmy specifica-tion, in which- Figure l, is a. side elevation of thepincers and wire. Fig. 2, is a longitudinal section through the center,the pincers being open; Fig. 3, is an end view showing the mouth of thepincers in a closed state. Fig. t, is a plan of the pincers and part ofthe cloth and wires. Fig. 5, is a side view of the pile wire.. Fig. 6,is a. cross section t-hereof on the line A, B. Fig. 7, is another crosssection on the line C, D, Fig. 8 is a plan sho-wing a modified form ofthe pincers. Fig. 9, represents a part of the cloth and wires with thepincers.

The same letters indicate like part-s in all the figures.

In my patent for improvement in looms for weaving coach lace,&c.,granted April 20th 1837, the pincers are represented with iat jawsof the width of several wires, which wires are round and of a. uniformsize their whole length. My present improvements are mo-re particularlyapplicable to flat or oval shaped wires which require to be kept withtheir edges upward during the operation of weaving, but they may be usedto advantage in working round wires. In my improved pincers the faces ofthe jaws are made narrow,--that is about the width of a pile wire,-andgrooved to conform to the shape of said wire.

The nat-ure of my invention consists in making that part of the wirewhich is grasped by the pincers wedged form or oval shaped, so that itwill readily enter the grooves in the jaws of the pincers, and beprevented from turning therein when grasped, said grooves being made toconform to the shape of said wire.

Fig. 5, represents the novel part of my improved wire wit-h a portion ofthe part which works in the cloth broken off. Fig. 6 shows the shape ofthe part which is grasped by the pincers, and Fig. 7, that part whichworks in the cloth. Figs. l and 2, represent the pincers, the generalconstruction of which is the same as those in common use.

(ce) is the upper blade or jaw and (o) is the bottom blade or jaw of thepincers.

(o) is the latch which holds the pincers in a closed position, and (CZ)the spring which throws them open when the latch (o) is released.

(o) is the stand which carries the pincer blades or jaws.

Fig. 3, represents the mode of grooving the jaws of the pincers toreceive the wires. By inspecting these grooves in the jaws of thepincers and the shape of the wire in Fig. 6 it will be seen that theyconform well and readily 'engage with each other when the pincers areclosed upon the wires.

I employ t-hese pincers to' successively draw out the pile wires fromthe clothcarry them back toward the lathe, insert them in the open shedsof the warps. The pincers are then opened and moved forward toward thebreast beam to seize another wire. I also employ the pincers in a mannerto grasp the wires without their having been previously pushed towardthem, and to prevent the pincers from acting on more than one wire atthe same time, I make that part of the jaws whichgrasp the wir-es,narrow as represented in Fig. 4. To prevent the pincer stand from comingin contact with the lathe I sometimes bend the pincer jaws back asrepresented in Fig. 8. This however is not necessary when the shuttlebox on the side of the loom where the pincers are located is madeseparate from or made movable as regards the reed whereby it will notadvance far enough to come in contact with the pincer stand when thelathe beats up. The pincers may also be prevented from coming in contactwith the shuttle box lathe when it beats up the cloth, by causing thepincers to move forward toward the breast beam, that is to say, afterthe pincers have drawn a wire from the pile, and the lathe is advancingto beat up the cloth, the pincers move forward carrying the said wire atthe proper time to clear the lathe, then move back in conjunction withthe lathe to insert it.

I employ these pincers in connection with a guide or guides to supportthe wires after they are drawnfrom the clot-h, which guides move forwardin unison with the pincers to carry the wires in succession to the pointwhere they are to be introduced into the open shed. VFig. 9 representsthe pincers with a. wire drawn nearly out of the cloth. (f, 72)represent the guides for supporting the wires7 an end view of one ofwhich is given in Fig. 10. These guides are mounted on an axis over thewires and are provided with an opening in their lower ends for the Wiresto slide through. They are also made to open and close. They open toallow the pincers to pass as they advance and recede from the cloth towithdraw and insert a Wire; but are closed to encircle the wire when itneeds to be guided /or supported. Then very long Wires are used; so asto require additional support, guide plates may be made to rise upbetween the warps for the wires to slide upon, similar in form to thatrepresented by (g) Fig. 9. These guides are not generally requiredhowever in weaving cut pile fabrics as the ends of the wires opposite tothe pincers may be turned up in the form of an eye which rests upon thewarps and forms a sufficient support to the wires as it is introducedbetween them.

Having pointed out the nature of my nvention and its mode of operation,I would remark that I do not wish to confine myself to the precise formof the parts represented nor do I claim as new constructing pile wireswith heads or eyes; for this is the usual mode of constructing them forhand looms; but

lVhat I do claim and desire to secure by Letters Patent is,

Making one part of the pile wires which is to be grasped by the pincerswedged form or oval shaped in combination with grooves in the jaws ofthe pincers to conform thereto substantially in the manner and for thepurpose specified.
